Customer feedback on social media has become invaluable to private businesses in recent years. Now, cities like Washington, D.C., are turning to it to grade their agencies.

Citizens' feedback doesn't always make it to the public employees who need to read it. The District of Columbia has contracted with an Internet company to compile citizens' comments from social media, post them online and use it to create report cards for ten of the District's agencies, reports The Wall Street Journal. Citizens and public workers can view the grades and the compiled comments on Grade.DC.Gov. The site allows employees to interact with citizens more directly and receive both praise and criticism, which can be used to improve services and spark motivation. Since the project began in June, over 24,600 "insights" have been collected. It's estimated by the mayor's office that the program could cost $670,000 for the first two years.
